Patent CA-2282245-A1 (CA)
Inventor: MIRIELLO VIRGILIO
IPC: H04B10/00
Filed: 1999-09-15
Abstract: A method for detecting a break occurred in an optical link system and quickly and accurately locating the position of such a break. The present invention provides for the use of an alarm indication signal (AIS) of the SDH regeneration section in a non compliant interface of the optical transport network. The basic idea consists in extending the application of the Alarm Indication Signal to the regeneration section of the SDH link layer. With the introduction of the Optical Layer, as lower layer in the Transport network, the event of the break in a cable as a fault condition in the Regeneration Section of an SDH network is replaced by the cable break event in the transmission section of an optical network. The tributary of the WDM terminal will construct an SDH-compliant Alarm Indication Signal as a result of the break in a fiber or of the reception of a lower or server layer fault signal. As a result, the SDH network manager will not be led in error as to the fault location.

Title: Method for secure key management using a biometric
Inventor: STOIANOV ALEXEI
IPC: H04L9/00
Filed: 1998-04-20
Abstract: This invention describes a secure method for consistently reproducing a digital key using a biometric, such as a fingerprint. The digital key is linked to the biometric only through a secure block of data, known as the protected filter. The key cannot be released from the protected filter other than via the interaction with the correct biometric image. Once generated, the digital key may be used in a system as an encryption/decryption key, or as a personal identification number (PIN).

IPC: H04L69/14
Filed: 2000-06-20
Abstract: An improved rotary hearth furnace having a cylindrical enclosure containing a radially moving belt for transporting pellets containing metal oxide and carbon is disclosed. One or more oxy-fuel burners preferably having a flat flame shape are positioned so as to provide a mixture of fuel and oxidant to the pellets countercurrent to the direction of the pellets. The oxy-fuel burners are operated so as to provide a pre-determined quantity of oxygen in addition to that necessary for combustion so that the additional oxygen oxidizes the carbon monoxide and hydrogen present in the hot combustion gases. Oxygen injectors may also be used to introduce additional oxygen into the furnace. The additional oxygen is strategically injected into the furnace based on thermodynamic modeling of the furnace so that a substantial majority of the fuel is introduced in a reducing zone so that the reducing zone has a fuel-rich atmosphere while the oxidant is primarily introduced in the heating zone so that the heating zone has a fuel-lean atmosphere.

Patent CA-2332498-A1 (CA)
Inventor: MARKS DE CHABRIS ANDREW
IPC: G06Q40/00
Filed: 2001-01-26
Abstract: A order matching system which allows users to define and modify buy/sell order schedules for execution within one or more transaction destinations. The system uses order schedules and associated evaluation heuristics to evaluate and update order characteristics such as price and quantity based on user-specified criteria. The matching system comprises a user interface which can be connected over the Internet to various transaction destinations through a schedule manager and a transaction order interface. The user interface provides users with the ability to obtain information concerning the status of their order account as well as the ability to enter or modify their order schedules. The order manager uses a schedule supervisor server to maintain a database containing order schedules and order status information and to execute variable evaluations on the basis of these order schedules and associated evaluation heuristics. The order manager also uses a transaction supervisor server to monitor the status of order fills and to update the database periodically. The transaction order interface receives and communicates information messages between various transaction destinations and the schedule manager. In this way, the order matching system allows users to specify the ways that various terms and conditions at which they are willing to transact may change over time in an automated fashion while still retaining the ability to intervene at any time.

IPC: C22B19/02
Filed: 1999-06-04
Abstract: The invention relates to a method for recovering non-ferrous metals, particularly nickel, cobalt, copper, zinc, manganese and magnesium, from materials containing said metals by converting said non-ferrous metals into sulphates by means of melt and melt coating sulphation, i.e. by a thermal treatment under oxidizing conditions within a temperature range of 400 to 80 0 ~C, during which a reaction mixture is formed containing at least one said n on- ferrous metal, iron(III)sulphate and alkali metal sulphate, and appropriate reaction conditions are selected to substantially prevent iron(III)sulphate from thermally decomposing to hematite, and finally, said non-ferrous metals  are recovered as metallic compounds. In the method of the invention, a proce ss is formed around the melt and melt coating sulphation, which comprises nine steps. The invention is particularly characterized by the manner of pelletizing the material to be fed into step 2 with an alkali metal (Na, K) sulphate - sulphuric acid - water solution, during which the hematite (Fe2O3 ) contained in the feed material will at a suitable temperature react with sulphuric acid and form hydrous iron(III)sulphate which together with sodium  sulphate also acts as the bonding agent required in the pelletizing.

Title: Method of monitoring the competitiveness of a microbial strain
Inventor: VEGARUD GERD
IPC: C12Q1/6888
Filed: 1998-09-11
Abstract: A method of selectively monitoring development and/or competitiveness of a microbial strain in a sample environment, comprising inserting a selectively detectable genetic label into the strain and adding the labelled strain to the sample environment and isolating DNA or RNA of said strain from the sample environment and detecting the amount of the genetic label. The method is also used for selecting, among a multiplicity of microbial strains, the strain that in a pre-selected environment and under pre-selected conditions has the highest capability to survive, multiply and/or express a pre-selected gene.  The amount of genetic label is detected by PCR including a PCR technique that is capable of detecting a label consisting of a single nucleotide substitution, including a technique where the first PCR cycle involves the use of a reverse transcriptase. The method is also useful for establishing the identity and origin of a microbial strain by inserting a genetic label comprising a coded message.
